The short answer
On a Electrolux dryer, a noise that was not there before usually comes down to the vent blower rather than anything deeper in the machine: the blower wheel sits on the motor shaft and clatters against its housing once its mount softens. That keeps it an owner check first, not a service call. Start here: turn the drum by hand and listen at the front, because on this platform the front felt support wears through before anything at the rear.
What you are seeing
- A low rumble that rises as the load gets heavier
- A squeal once per drum revolution
- A metallic rattle that carries on briefly after the drum stops
- A scraping that stops the instant the drum stops
- A hum with no drum movement at all
- Not this fault: A hum with no rotation, which is a drive fault rather than a noise fault
- Not this fault: A thumping that is really a zip or a buckle in the load, which is not a fault
- Body: Electrolux builds this dryer as a twenty-seven-inch cabinet with front drum felt supports, a rear drum bearing and a blower wheel on the motor shaft. That architecture decides which of these you see first.
- Also check note: If these fit better, the fault is a different one.
Likely causes, in order
- The vent blower — Why this rank: The Electrolux blower wheel is pressed onto the motor shaft and works loose, producing a metallic rattle that comes and goes with speed.
- Worn front drum glides — Why this rank: The Electrolux front drum support is a felt strip that wears through to metal, giving a scrape that stops the instant the drum stops.
- An object in the blower path — Why this rank: A coin or a button in the blower housing rattles hard and is the cheapest fault on this platform to find.
- Worn drum support rollers — Why this rank: Rollers wear oval and produce a low rumble that rises with load and follows the drum exactly.
- A dry idler pulley — Why this rank: The idler pulley bushing dries out and squeals once per drum turn.
- Body: Ranked for a Electrolux dryer specifically.
What to check, in order
- Body: The order follows the ranking, and the ranking follows the platform. First: run the fan alone and listen with the oven not heating. It goes first because the Electrolux blower wheel is pressed onto the motor shaft and works loose, producing a metallic rattle that comes and goes with speed. Second: press down on the front of the drum through the door opening. With the first check clean, this is what the Electrolux platform makes next most likely. Third: look into the blower path through the filter opening with a flashlight. Only after those three is it worth reaching for worn drum support rollers: it costs more to get at, and it does not explain the first three coming back clean.
Checks you can make
- Run the dryer empty for a moment and then stop it. A rattle that continues briefly after the drum stops is the blower wheel coasting, not the drum. — Tools: none — Time: about five minutes
- With the machine unplugged, turn the drum slowly by hand through several full turns and listen at the rear. A rumble that follows the drum is the supports; a squeak once per turn is the idler. — Tools: none — Time: about ten minutes
- Reach through the lint filter opening with a flashlight and look for coins or buttons sitting in the blower path. — Tools: flashlight — Time: about ten minutes
- Open the door and press down and then up on the front of the drum. Movement with a scraping sound is the front supports, which wear before anything at the rear. — Tools: none — Time: about five minutes
- Body: Stop at the first step that would need a meter on live terminals or a sealed assembly opened.
Before you open anything
Safety
Treat a dryer complaint as a fire question first. Heat, lint and restricted airflow are the combination that starts laundry fires. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Clear the whole duct run, not just the machine end. A restricted duct is the condition behind most dryer heat faults and behind most dryer fires. Never run the machine with the duct disconnected for longer than a brief test, and never vent it into the room.
When to call
The line is not difficulty, it is what the next step costs and risks. Call when: the drum can be moved up and down by hand in a way it could not before a metallic grinding has appeared and is getting worse within a single cycle the noise is accompanied by a burning smell, which means stopping immediately
What this page omits
This is generalized information: it ranks causes for the Electrolux dryer range as one platform. It does not cover model-specific variation — a board revision, the system fitted to one production run, or a bulletin covering a single model family. Where a page exists for your specific model, that page is the more specific one and takes precedence over this. Read your model number off the rating plate before ordering any part.
